[gse-aa] Auroral Alert

[cdeehr at gi.alaska.edu]

A very bright solar event took place on September 7th around 5:45 pm Greenwich
Time.  It is not directly facing Earth, but the shock wave will combine with
that of an earlier event to produce a significant effect at Earth.
  
We predict that it will arrive on Sept 9 around 11 am Greenwich Time.  Because
it will arrive in the morning in Europe (early morning in the US), its effects
will be seen first in southern New Zealand, Tasmania and Siberia.  Depending on
the nature of the shock, there should be aurora visible in southern scandinavia,
Scotland and northern US on the evening of the 9th.

Note that this event could be followed by others of similar magnitude as the
active region (No. 0808) moves westward accross the sun, facing Earth by the
weekend.  This could result in aurora for the middle US  and Northern Europe.
